To all whom it may eoncern:

Be it known that I, ROBERT ,C'UMMiNG ANNAND, of Cornwallis street, South Shields,

Durham, England, printers engineer, have .matrix has to -be stripped from the late and ie-setin position in the casting ox each time a plate is cast. This consumes much valuable time and in the specification of a previous application S. No. 352,695, filed 17th January 1907 I have describeda method and means whereby semi-circular or curved stereotype plates can becast and stripped successively from a .matrix kept fixed in a rigid casting box. According to the said method this result is attained by bending the cast plate inwards on the core to allow it tol be stripped thereby from the fixed matrix and moving the core and cast plate away Ifrom the matrix to effect this stripping operation. The necessary clearance-between the core and matrix to permit of thus bending the plates may, as described in the said specification, be 4created by collapsing the core with the plate attached thereto, or by employing a non-collapsible core and providing means whereby, when the core to which the plate when cast adheres is moved out of the 'casting box to strip the plate, this latter is temporarily delayed from following its Ainotion. For the purposes of the present inven-` tion it is preferred to employ such a'method of stripping the plates successively from a fixed matrix, but I do not confine myself to such employment. 'i

The invention comprises a casting box .shell and a boring box shell arranged to reciprocateon a slide adjacent to a movable core and apparatus for supplying molten metal to the casting shell, in combination with boring and delivery mechanism for the cast plate, the wholi being so arranged and operated, that the casting and boring shell can be brought alternately opposite the core, which first coacts with the casting shell to cast the plate, then moves out with the cast plate and delivers it into the boring shell when this slides to position to receive it, the boring shell then in its return motion carrying the plate to the boring .apparatus while the casting shellreturns to its position in relation to the core, so that a second late can be cast while the preceding one is eing bored and expelled from the boring shell. In conjunction with such an arrangement it is preferred to employ devices whereby the straight and circular edges of the cast plate are respectively trimmed during the return travel of the boring shell from the core and the delivery motion of the plate.

The invention also comprises the combination with such arrangement 'of a shaft. set parallel to the slideon which the casting and boring shells travel, and carrying a series of cams whereby the core and some or all of the other machine elements involved in the cast- Ving and manipulation of the plate are operated and controlled. l i n The invention also comprises in combina- -tion with an arrangement of the character mentioned and wherein a collapsible core is employed, a parallel cam shaft disposed as above stated and carrying cams adapted lrespectively'to collapse and expand the core,

withdraw a bar by which the bottom of thecasting space .is closed, raiseand lowerl the '.coi'e into and from the casting and boring shells, operate a device for breakin of the jet, actuate a device for strippin tie plate from the core into the boring shel operate a devicefor expelling the bored plate from the' boiiiig shell and controlV the operationof a pump to supply the metal to the casting shell. The said'cain shaft may also .carry a-cam for effecting the reversal of the sliding move;

ment of. the castingv and boring shells.

The invention further comprises the employment in apparatus for casting andborino' curved stereotype plates, of a core adapted to move into and out of a casting shell and a boring shell alternately for casting a plate and transferring the same from the casting shell into the bo'ring shell, in combination with a moving member or mouthpiece component on' the core and means for projectingV the same .against the jet when thecore'has ico -fositedvthe plate inthe borkig Jreakyolthe jet over the ed. shell.

To facilitate the following description l will shortly summa ze the aetion of the machine illustrated, rlhe matriz. .havinglbeen iiried in the casting shellaiid the ma.

chine-started, the -csstihg shell sli les. to' position opposite the spout ci 'the melting pot,

lthe core descends vinto' the casting shell arid vthe pum is operated to' supply the metal to the' mol and the machine stops. When the `plete vis suiiciently set the machine is', started, the cere strips the plate from the matrix and' fses With it out of the casting shell, the casting-and boring shells slide along. until the boring shell comes under the core, which descends and deposits the plate in the boring shell. T he jet is broken oli over the top of the boring shell The core rises and the casting and boring shells slide back to -bring the casting shell again opposite the spout 'and the plate iii the-boring shell under the boring trimming and delivery mechanism. While these are 'dealing With thev cast plate the pump is operated to cast theiiext plete, land so on.

l. 2, 3 are the main frames of the ma.-

4 ehines which comprises e melting pot l disposed about midway 'of its length. it the lower part of the machine is mounted a slide 5 'extending for its length and upon this slide v"the casting and boring shells 6 and 7 which VVV'arelroiinected together as described later.

'8 is the-'delivery table and 9' the motor.-

.T he frame 3 V'carries all the main driving gear Which receives its motion from the driving belt l() running on the fast and loose pulleys ll and l2 respectively. The main driving shaft i3 is out with a Worm le at the o`p ia shoulder 15 which huts against ball thrust bearings 16; The Worin le gears with a Wheel 17 keyed to theV trumiions 18 of the boring and delivering cylinder 19, so to drive this always in one'directioii. On driving shaft i3 is mounted a gear Wheel 2O meshing With a gear Wheel 2l oil-the countersliaft 22. Shafts 13 and T22 are supported iiibearing brackets 23, 23, 2e of which 2st may he adjustable longitudinally for Wear.

Keyedjoii shaft 22 are a oafpstan' 25, a sliding clutch 26 and a Worm 2-7. The latter drives a worm Wheel 2S iXed on a @am shaft 1391. mounted parallel to the slide 5 and carry-l ing the Various cams which control the -opf eratioiis of the different parts of the machine. -Loose on shaft 22 are ruiter Wheels 3Q, 30 meshing with a initer Wheel 3l keyed on the through shaft 32 of a drum 33. The shaft 32 is mounted belowthe slide 5 and extends oosite eiid from the-driving pulleys and has j the whole leiigth of the machine. The drum 33 1s formed with a spiral groove 34.` rlhe reciprocating travel is ini arted to the casting and boring shells 6 am 7 on the slide 5 hv the drum 33. During the operation of the machine the clutch 26 is slid into gear with the niiters 30, 30 alternately, under'the action of a cam on the cam shaft 29, and thus is provided to secure the correct relative po-A sitions of the shells.

The drum 33 With spiral groove 34 extends about half the length of the machine and the bottom of the casting shell carries a roller37 'yyf'orking in the groove 34, so that as the drum 34 rotates in alternate directions,

- the casting and boring shells are driven al- .ternately in op osite directions and come in turn opposite tie melting pot spout 38 and core 39, which are located at vabout the middle of the machine AandY the boring shell comes alternately'opposite the boring knife on its cylinder 19. The groove 34 has a plain circular ortion 34 at each end so as to insure that t e shells 5 and 6 liall come accurately to their end ositioiis without shock. The drum 33 is at justable longitudinally to take up wear by means of nuts 40 at each end, the thrust of which is taken by ball bearings 41 at the ends of the slide 5.

The sliding motion of the clutch 26 `to engagethe miters 30, 30 alternately is inito an arm parted by a fork 42 (Figs. 2 and 13) fast on a rod r43 sliding in a braeket44 and connected This arm has a rigid connection tothe shaft 46 mounted in the frames 2 and 3 and through it to the arm 47 which carries a roller 48 working in a groove 4f of the 'cam 50 (see Fig. 13). l

' The casting and boring shells 6 and7 are approximately seinicireular. castings properly faced to run on the slide 5 and provided with gibs 51 working on corresponding guide surfaces 52 at the sides of the slide. h

vset in a tilted position as shown with their They are backs lto the melting pot and their concave faces towards and parallel to the cam shaft 29.

The matrix is permanently clamped in the casting shell for 'the whole run. For this purpose it is preferred to employ t-lie matrix @clamping arrangement illustrated in Figs.

6', 7 7. Referring to these iigures, 53, areloose side gages disposed in the casting shell 6 these being adapted to suitably overlap the matrix at the sides and being inserted .less on the matrix.

4prior specilication.

in the shell 6 by a seinieircular feather 53 with' which they are each formed. said feathers litting in grooves in the shell and preventing the side gages from slipping out when released. The top and bottom edges of the matrix are clamped by rocking grippers 54, 54, mounted on spindles 55, 55 controlled by hand levers 56, 56. `The hand levers are locked in the matrix clamping position by spring plungers 57, 57 on the ends of the hand levers and cach adapted to engage in a suitably positioned hole in the shell 6.

In order that the grippers may always hold the matrix firmly, an adjustment is piovided whereby theangular position of the plunger relatively to the gripping edge may )e varied to cause said edge to bearmore or This adjustment in the case of both gripper's consists of an arm 5S keyed to the respective spindle 55 and formed with segmental slots 59. The bosses of the hand levers encircle the spindles 55 and the hand levers are adj'iistably secured to the arms 58 by bolts 60 passing through the slots 59. To adjust the gripping` pressure on. the matrix, the plunger 57 is engaged in the hole in the shell, the bolt 6() is loosened the pressure is adjusted and the bolt tightened up. The top gripper 54 also serves to clam p the side gages 53 and hence the side edges of the matrix in positionfby means of a projecting edge 61 of the'same thickness as the matrix,

formed on the upper edge ot each side gage and which therefore abuts against the top gripper when this is turned to clamping position. The lower ends of the grooves in the shell for the feathers 53 are undercut as indicated at 62 and the feathers are shaped to correspond, and by this means together with the gripping of' theprojecting edges 61 the side gages are prevented from springing in with the newly last plate when the core is collapsed as described later.

The matrix clamping arrangement shown in Figsl 1 to 3 dilleis .slightly from that just described in thatthe top gripper 54 is arranged to be swung into and out of the position in which it clamps the matrix and side gages, by means of forks 54() (Figs. 1, 1il and 3l attached to the spin dle 55() on which the gripper 54 is mounted, the forks leing'operated by an eccentric rod 551 by means of a handle 560, so that when this handle is thrown ovei, the gripper is rocked into and out of its clamping position. lhis is a similar arrangement to that adopted in my said ln other respects the arrangement ofthe gages andfclamping meehanism is as before described with reference to Figs. 6, 7, 7u.

The core 39 is arranged to be collapsed to enable the east plate to be stripped by it from the fixed matrix. lt is eomposedol two hollow semi-ey-limlrical segments 39, 39 hinged together at each side by hinge or stud pins ving surfaces embracing the hinge studs 69 v which projectl through bosses 71 of the rock-. ing levers 7'2 winch osclllate about the renier in Fig. 7b, in whicn 39 designates the core,v

69 and provided at the hinge joint with registering grooves 690 (Fig. 3h) for the recep tion of *asbestos piu-king. The hinges consist ot members 70, 70*l bolted to the respective segments and having semicircular Vbearof a shaft 73 mounted in the frames 1 and These rocking levers are controlled by av pair of cams 74, 74 (see Fig. 9) on-the cam shaft 29 by rollers 72"i working in grooves 74L of the earns 74. levers 74 isyto move the core into and out of the casting and boring shells at the proper times. The rollers 72a respect to the levers 72 in slots 72b.

The core is collapsed and expanded at the proper tinies by mechanism follows to them the lateralV end pieces 91a. close the ,sides of the curing mouthpiece.'

75 is a sha-tt journaled in the rocking levers "2 upon which bell .cranks 76 are keyed at .each side of the core between same and the rocking levers.. levers nre connected respectively to the core segments by links 7,7, which may encircle eccentric bushes supported by studs in the core so to provide adjustment for wear. )ne end ot shaft 7.3, projects through the out side rocling lever (the right in Fig la) end upon it secured an arm 78 connected. by a link 79 to bell crank 80 supported by the rocking lever 72 (see VFigs. 1.a :ind 8'), Bell crank 80 carries a roller S1. running in the groove 82 or' cani 33 'on cani shaft 29 and.

which controls the motions of the described mechanism Vtor opening and closing the core.

The rocking motion ot the roller 81.- due to the oscillations or the rocking levers 72 does not atleet the proper operation ot the openn ing and closing ol' the cose, as the tangent oli'l the middle point oi the arc, described by the center or 'the roller, is. also tangent to the middle line of the concentric portion ot thel cani groove, that is to say an imaginary line rui ng round the middle of the concentric portion oi' the cani groove. .Y I

The core is fern with parallclgrooves ,as

'usual into which the niet-al runs to 'torni the y out these ribs on the inner Atace ot the plate, grooves are' slightly undercut at the 'bottoni andv rounded at th'e'shoulders asillustrated 39b the cast plate and 39d the instriX/:in this way the `cast plate will adhere sulliciently to the core to he bent inwardsl thereon when the core is collapsed to strip the plete lroin theV matrix.

The bottoni olA the casting` the core and matrix. is closed 'at the proper times by two coacting bars Sli, 85. .Bar del is dovetailed. into the core, while bar is secured to rocking arms 80, 86 (Figs. 1, f1, 3

space between and 10) to' which are linked iorked'levers 87, 87, the forks oi which slide on the cani shatt- 29. The levers 8,7l carry rollers 88 'working The function of the rockingl are adjustable with tive ends of the core and to which are screwed The arms ot these bell crank 'the sliding' y these tools essere l in the grooves 89 of earns 90 on the cam shaft.

l?.eciprocating motion is thus imparted to the levers 87 .and thus the stopper' bar 85 1s'. caused to rock towards and away Jrorn the cani shaft 29. The function ofthe stopper. bar is two fold, firstly it rocks nite pos1- tion against bari to close the casting space when the core has moved into. the casting i shell, and secondly when the core has strippe the plate from the matrix and descends with it into the boring shell when this v.has slid into positionl` the bar 85 rocks into position against the lower edge of the cast plate and acts to strip it from the core into the boring shell.

The pouring mouthpiece at the top is cornpleted by two fixed pieces 91 on the respecso.v

the ends 91L and' an'intermediate sliding member 92, the Vflied pieces 91 having screwe hich .rlliesliding member 92 las another function explained later. The front faces of 91 and. 92 are inclined and' are in alinement in the casting position of the parts, thus forming the inner wall of the mouthpiece 493, Fig. 3. The boring shell 7 is ofsiniilar forni to the casting shell'and is lined with zinc. At `top of its cast iron body is bolted a steel bar 94 which completes the seinieircular rece taele and is formed with. a's'trong Sharpe ge 95 extei'iding. the length. of the plate and over which the jet is broken off when the core delivers the plate into the boring shell.

The jet is broken off byf the member 92 betere mentioned, which conforms tothe shape ot the core 39 and slides thereon, L

being guided interniediately by slots 96 Working studs 97 on the core 39, Figs. 1, 1a and 11; The operation of the member 92 to retain it ing and slide it forward against the jet to between the end pieces 91 andA lover f i in alincrnent with the end pieces-91 for cast- I break this oil over the edge of the boring shell, lis controlled by c'aI'n 98 on earn shaft 29 as follows (Figs. 1, 1.a and 11').- g

99 is a lever niounted on shaft' 7 3 asa .tulcruin and guided bya roller 100 workinginl the groove 101 ol the cani 98. The top end ci lever 99 carries a pin .102 working inY the slot 103 oi' a connecting member 92'.

Tl e usual edge tools for trilnining thev v125'v straisdit edffes ol' the late in the borinCr shell D 'D D link 104 ettaehedby -an adjustable cross headr105 (Fig.` 1', 1) to yshown as connected direct to the sliding are attached to the trarne f2 over the path which these edges 'traverse as the boring shell .slides to the boring position, vsothst as the slides into the boring positionl boring shell trim lille straight edges' o f' the plate. This is a commom arrangement and will be understood without further illustration.

The boring and delivering cylinder 19 in its 0feneral arrangement is similar to that described in my said previousapplication. l It is mounted in the frames 2 and 3 and is driven in a constant direction by the worm wheel 17 as described. It carries a boring knife 107 andan automatically retractable driver bar 108 at opposite sides (see Fig. 14)4 and is formed with segmental ribs 109 which strengthen it and serve to support the plate during trimminer of its circular edges and delivery. The cylinder 19 is located over the position into which the boring shell 7 slides with the cast late, and is concentric with the boring shell. Dorinep the time the boring shell is sliding with the plate to position under the boring and delivery cylinder 19, the boring knife is describing a: semi-circle clear of the plate and the driver bar 10S is kept retracted so that it clears the plate in the boring shell. lhen the `late is in the boring position the boring ynife 107 describes its operative semi-circle 'and bores the plate i. e. shaves the ribs cast on its inner face, the driver bar 10S being meanwhile projected as about to be explained so that in the succeeding half revolution of cylinder 19 it comes against the lower edge of the plate antidrives itround before it out of the boring cylinder 7 and on to the ribs 109 for delivery.

'lhe driver bar 108 extends the length of the boring cylinder and is guided in its projection and retraction by inclined slots 11() in it working over bolts 111 by which it is attached to the wing 112 of the cylinder. A link 113 is connected at one end to a driver bar 108 by a stud 114 and at the other end to a guide -115 having projecting lugs 116 to take the end of the link. The guide 115 slides to and fro in the direction of the cylinder axis on two bed keys 1.17 being actuated by two levers 118 with rollers 119 working in a circumferential groove 120 of guide 115. Levers 118 are similar to a lever 121 the roller 122 of which works in thegroove 123 of a eam`124 (Fig. 141) on cam shaft 29.- The levers 118.121 are lixed on a shaft 12,5 located in eyes 126 secured to the frame 3. Thus by the action of the cam 124 the guide 115 and links 113 are slid to and fro in the direction of the axis ofthe cylinder 19 and the driver bar 10S is projected and retracted at the proper times. d

W'hile the boring knife 107 is boring the plate this is prevented from sliding out o1` the shell 7 by a bar 127 which is moved against its lower edge at the proper time and immediately the knife leaves the plate this har 127 by the driver bar 1.08

1s moved down clear of thc path the platte will take in heilig driven 'round out of the shell These movements ot' the bar 127 are effected as follows (Figs. 1 and 12). The bar is carried by two arms 12S keyed to a shaft 129 mountedinframes- When the boring is completed, the bar 127 moves away from the late and the driver bar 108 comes against t e u per edge ofthe plate and drives it round be ore it on to the ribs 109 ofthe boring cylinder for delivery. In this rotating movement the curved edges of the plate are trimmed in the known way by adjustable cutters 134 mounted on a shaft 135 supported in the frames 2 and 3, one of these cutters is shown in the ligure, the other being identical.

To prevent the late from falling from the boring cylinder w ile being delivered, there are two wooden rollers 136 (Figs. 1 and 2) supported by an arm y1.37 pivoted on the shatt 129 ant subject to the action of a winding up spring 13S, which tends to keep the rollers 136 up to the surface of the plate. Rollers 136 are covered with stereo blanketmg.

The machine stops automatically just after the finished plate is clear of the boring shell, the )late is not delivered on to the table S till tlhc machine is started on a second cycle. 1f it should be required to lift the finished plate from the machine before its final delivery the rollers 136 can be raised by hand and the plate removed. i

'Vlie machine is automatically stopped with a finishtd plate ready for delivery and the next one cast in the mold, by the following mechanism illustrated in detail in Fig. 15, where it is shown in the stop position. is a shaft journaled in the frames 1 and 3 on which are keyed at any convenient points any desired number of hand levers 140, for starting or stopping; one lever is shown. Keyed on shaft 139 outside frame 3 is a toothed cuadrant 141 meshing with a rack 142 on the rectangular' striking lever 143 sliding in brackets 144 on frame 3. 1-15 is a latch pivoted on a plate 1-16 fastened to the worm Wheel 2S and adjustable thereon by slots-147. The latch thus rotates with the .Worm wheel. By means of a spring 149 it is kept projected so as, in its revolution, to engage a trigger 150 keyed to shaft 139 and thereby at the proper moment turn the shaft 139, whereby the quadrant 1-11 moves the striking rod 143 to throw the belt on to the loose pulley 12. While engaging thetrigger 15() the latch 145 is prevented from being depressed hy a projection 151 on the bracket, 1-1-1. ln the lstop position the latch is just clear of this projection. A stop 152 on the plate 116 prevents the latch risingl too high under the action of its spring. When the operator throws over the hand lever to start soV the machine on the neXt cycle, the latch and trigger move clear so, that the latch can rotate with the plate 146.

The metal is supplied from the melting pot 'to the casting box by a pump of usua construction operated by the descent of a weight (rig.

153b mounted on the melting pot 4. The pump is operated at the proper period by mechanism as follows. (Fig/ 5). 153c is 'a .shaft mounted in the framework 153b and rocked by an arm154 keyed thereon and l connected by a rod 155 oi adjustable length trolled-by the cam/159 which through the lever 156 and thedescribed connections lifts the piston against theaotion oi the weight 150'. lfiflien the step of cam 159 reaches the rollers L58 the weight is released and falls,

' except along a line at the hinge center.

ioroing down the pistona.nd*diseharging the metal from the pump cylinder through the spout 38 into the casting box; The weight strikes the ground at the endl of thel down stroke, which can beregnlated by screwing theweignt up or down in its suspensioneye 165 by a handwheel 165. The Weight 160 is guided ina casing 16.7.

All the eams which control the motions of the Azmachine .as'd'escribed are mounted on bosses keyed tothe cam shaft 29 and are adjustable relatively 'to the. bosses in the manner shown in 3 with respect to cams 74,

7.4, viz., by boite and slots 15S, 159.

The operation ol' the machine is as follows, starting y from the commencement of the cycle. 'Supposing a newly cast plate to have suiiiciently cooled the machine is started by a. hand lever 140. rlhe stopper bar 85 which closes the casting space, immediately, under the action of the cams 90, moves clear of the motions oi the plate. 39a of the ocre close underlthe action of. cani Sil-bending the plate inwards with them and stripping it from the fixed matrix at all points The core now rises with the plate under the ac- Y tion or" cams 7 4, 74 and rocking levers 72., 7 2,

so that the casting and boring shells 6 and 7 are free to slide under the action of. the spirally threaded drum v33, which immediately drives them to the right, bringing the boring shell 7 to position under the raised core.

The core again rises, and-as the stopper bar has been meanwhile removed by the cams into position to engage the bottom edg'e 0i' the. plate, this is stripped from the core into the boring shell,r thev top part of the plate having been loosened by the action of the breaking off wedge. The shells 6 and 7 slide back to the left to bring the boring shell V7 under the boring and delivering cylinder 19 l and the casting shell' opposite they spoutl 38. During this traverse the boring knife 107 will be 'describing a semicircular arc clear of the plate,.the driver barI 108 will be kept retracted clear ol' the plate by the cam 124 (Figs. 14, 14a) and the stopper bars S5 and 127 will be kept by their respective cams 90 and 133 in a suitable position to prevent the plate sliding ont oi the boring shell by gravity. luring this traverse ol' the shells 6 and 7 also the straight edges oiy the plate are trimmed as explained. immediately the shells come to position as described the knife 107 begins to bore the plate, the stopper bar 127 remaining in position to hold the plate until the boring is complete, when it immediately moves down and at the same time the driver bar 198 is proie-ated and comes against the upper edge of the plate, which it drives round belore it on to the ribs 109 of the boring `cviinder 19, where it is held ready lor delivery by the rollers 136, the curved edges being trimmed by the tools 134 as the platerotates. The machine then stops automatically onder the action oi the mechan.

Von a new cycle, the finishedA plate being de livered on to the table 8, on to which it is guided by the project. ag :edge 8a., Fig. 2. As I the plate leaves the ribs oi the cylinder 19 before being clear ,ci the rollers 136 these yield to the movement oithe plate while When the required'number oi plates have been east, the pump supply is diverted into the melting pot 5 by, a sluice 170 (Figa) operated by a handlever 171 ythrough suitable linkage so that the machine may complete and deliverv the ylast plate-.without pumping a new'supplyl .of metal into the mol lilnyorder to facilitate an understanding 'of the relative action and timing of the various cams to cast and manipulate the plate, a circle is described round each of the cams shown separately in Figs. 8 to l() and ll to 13, these circles being divided into arcs A M The cams are shown with the grooves in the positions they occupy relatively to their rollers at the beginning of the cycle. T he lettered arcs are supposed to revolve with the cams, and when the roller is moving in any given segment, reference to the following table will giveinformation as what is taking place in other parts of the machine at the time.

Start. A. Casting shell stopper bar 85 moves out. B. Segments of core are drawn together. @Core rises with plate out of casting shell.

l). Casting shell 6 slides away to bring boring shell 7 under core.

shell for next l Simultaneously with A, B and C of the next cycle the finished plate is delivered to 'the table 8.

The above operations A M are all effected during one turn of the cam shaft 29.

For the purpose of clamping the matrix in position at the commencement of the run, the machine will be started to bring the shells 6 and 7 to the right hand end of 'their traverse.

The segments of the core, the casting and boring shells and other desired portions of the machine, may be cooled by a circulation of Water or in other known ways.

The reciprocating motm .nav be imparted to the casting and boring shells by any appropriate mechanism other than that described and in general it will be understood that l do not coniine myself to the particular details of construction and arrangement described and illustrated as it will be apparent that the same can be. considerably modified Without departing from the spirit 'of the invention.

The invention has beenmore particularly devised for producingr semicircular stereotype plates, but it will be evident that it can be employed for casting segmental stereotype plates of other than semicirculz'xr dimensions.

Although the primary aim of the invention is to produce a machine in which the whole of the operations involved in casting and finishing the plate are performed automatically, as is the case with the ap )aratus described and illustrated, yet it will be understood that some of the combinations of parts or devices claimed may be employed in machines designed to be operated partly or entirely by the attendant. In the present specification and claims, the word iinishingwin accordance with the usual practice lseverally includes the operations ol boring and trimming its straight and curved edges.
